Well I think from SE's end, if they catch someone spamming people, not only should the account be banned, but the IP address used to access that account be blocked permanently as well. That would go a good way to putting an end to that. Secondly, they should add an invisible mode for everyone else. These spammers are using the player search function to get names to whisper. If we the players can invisible mode ourselves off of the player search function, that would help us too.
